摘要： A light pipe for separating incident light according to color, a color illumination system adopting the light pipe, and a projection system adopting the color illumination system are provided. Since the projection system is a single-panel projection system adopting a scrolling unit, its optical configuration is simplified. Also, the light pipe of the projection system is comprised of different-sized color separation units, thus improving the color gamut and the color temperature. Further, the light pipe includes color selection polarizers, each of which changes the polarization direction of a color beam with a specific wavelength, thereby improving light efficiency.

摘要： A projection system and a method of forming a colour image are provided. In this method, a rising time and a falling time required to change image signals for a plurality of colour bars formed on a light valve are secured. First, at least one filter having a slit is installed. Next, incident light is scrolled by converting a rotation of a scrolling unit into a rectilinear motion of a lens cell of the scrolling unit through which the incident light passes. Thereafter, a beam emitted from a light source is separated according to colour using a colour separator which comprises a plurality of dichroic filters which each transmit a beam with one length from the incident beam and reflect beams with other lengths. Then, a plurality of colour beams separated by the colour separator and transmitted by the scrolling unit are made incident on corresponding colour areas of the light valve, whereby a plurality of colour bars are formed. Then, a black bar is formed between adjacent colour bars by controlling a distance between adjacent dichroic filters or controlling a width of the slit.

摘要： A highly efficient lighting system, a scrolling unit, and a projection system adopting the highly efficient lighting system and the scrolling unit are provided. The scrolling unit has at least one lens cell. From the viewpoint of light incident upon the at least one lens cell, the rotation of the at least one lens cell is converted into a rectilinear motion of a lens array, such that incident light is scrolled. The projection system includes a light source, an optical splitter, at least one scrolling unit, and a light valve. The optical splitter splits light emitted from the light source according to wavelength. The at least one scrolling unit has at least one lens cell. The lens cell has an incident side and an emitting side and divides incident light into light beams. The rotation of the lens cell causes a rectilinear motion of the light beams, thereby scrolling incident light. The light emitted from the light source is separated into color beams by the optical splitter and the scrolling unit, and the color beams are focused on the light valve. The light valve processes incident light according to an input image signal in order to form a color image.

摘要： A high-efficiency, compact color illuminating system and a projection type image display apparatus using the color illuminating system are provided. The color illuminating system includes a light source, a spiral lens disc that periodically scrolls light by rotational movement, and an optical unit that isolates light beams of different wavelengths from white light emitted from the light source and guides the isolated light beams to enter at least two effective regions of the spiral lens disc. The projection type image display apparatus includes the color illuminating system, an image forming unit that generates images using scrolling light from the spiral lens disc, and a projection lens unit that enlarges and projects the images formed by the image forming unit on a screen.
